 A file has properties and text content; a directory has properties and children; that's how
it is in Subversion.  Saying that a user should be able to read part of a directory (its properties)
and not the other part (its children) is breaking that relatively simple abstraction, and
breaking abstractions in that way makes complications for all other software layers that try
to build on top of the foundation, not to mention for the users' mental models.  At first
hearing, it doesn't sound like there could be any major repercussions, but after a while I
suspect we might regret it.

Julian, I tend to agree with your objections, as indicated by my cautious wording. I was pushing
the envelope a bit since access control might be a significant hurdle for inherited properties.
